1. INTRODUCTION 1.1 General Description The continuity of electrical power is an essential requirement for critical load operations .The Uninterruptible Power System (UPS) is designed to meet the user‘s need of present computer, server and the equipment of office automation that make the UPS more compact and less noisy.
1.3 Important Notices To be sure that the UPS will operate correctly, the following items should be noticed: 1. Read instructions carefully before operating the UPS. 2. UPS power connection instruction should be followed. 3. Please don‘t open the case to prevent danger. 4.

2.2 Positioning 1. Do not put the UPS on rugged or declined surface. 2. Do not install the UPS system near water or in damp environments. 3. Do not install the UPS system where it would be exposed to direct sunlight or near heat.

2.4 Operation 1. Do not disconnect the mains cable on the UPS system or the building wiring socket outlet during operations since this would cancel the protective earthing of the UPS system and of all connected loads. 2. The UPS has its own internal power source (batteries). The output terminals may be live even when the UPS is not connected to the AC supply.
- use only tools with insulated grips and handles. 4. When changing batteries, install the same number and same type of batteries. 5. Do not attempt to dispose of batteries by burning them. This could cause battery explosion. 6. Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes.

Buttons Description When AC plugs in (UPS is not switched on.) this LCD display light will be on. UPS operation information can be seen including UPS status, input/output voltage, 1. LCD Display input/output frequency, battery voltage, battery capacity, load capacity, temperature, and event logs. UPS output voltage and frequency can be set from it here, too.
5. CABLE CONNECTION 5.1 Inspection 1. The system may be installed and wired only by qualified electricians in accordance with applicable safety regulations. 2. When installing the electrical wiring, please note the nominal amperage of your incoming feeder. 3. Inspect the packaging carton and its contents for damage. Please inform the transport agency immediately should you find signs of damage.
6. OPERATION 6.1 Check Prior to Start Up 1. Ensure the UPS is in a suitable positioning. 2. Check if input cord is secured. 3. Make sure the load is disconnected or in the “OFF” position. 4. Check if input voltage meets the UPS rating required. 6.2 Operation Procedure Please follow the instructions below for the UPS operation.

2. By pressing the Enter- key and the Down-key simultaneously for 3 seconds until the buzzer beeps twice, the UPS will start up and Normal LED lights up to indicate the power is from its inverter to the load. 3. When the LCD Select Down-key and the LCD Select Up-key are pressed simultaneously for 3 seconds until the buzzer beeps twice, the inverter will be turned off and the UPS is on the standby status (LCD display illuminates and Normal LED is blinking) until AC source is disconnected.

7.TROUBLE SHOOTING GUIDE 7.1 For LCD Model The following guideline may be helpful for basic problem solving. UPS STATUS POSSIBLE CAUSE ACTION AC utility power is normal. 1. Fan is damaged. 1. Replace the fan. UPS is running normally, 2. Unknown 2.
UPS STATUS POSSIBLE CAUSE ACTION AC utility power fails .The 1. AC utility power 1. Reduce the less load is supplied by battery failure. critical load in order to power. Buzzer alarm extend backup time. 2. AC input sounds every 4 seconds. connection may be 2.

8.2 Normal Operation There are two main loops when AC utility is normal: the AC loop and the battery charging loop. The AC output power comes from AC utility input and passes through static switch to support power to load. The battery charging voltage comes from AC utility input and converted by AC/DC charger to support battery-charging power.
9. COMPUTER INTERFACE 9.1 communication interface The communication interface (DB9 port) on the back of the UPS may be connected to a host computer. The port provides communication of RS-232 for monitoring software (like RUPSII or UPSilon 2000 of Megatec Company) The UPS communicates with the computer by sending out RS-232 data streams to one of the serial ports.
